What tow bar are you using?

I have the Curt bar with a set of Rock Jock tow bar mounts and a Brake Buddy. I have towed my Jeep from Oregon to Arizona and Arizona to Moab without issue.
 
Ready Brake & Brake Buddy research time.

LJ has Currie bumper with tow bar setup. No towbar. Brakes were setup for air activation by PO (motorhome I assume).
